If you're not getting your desired TH from your current setup, you may consider the following:
1) Your Wattage needs to be increased. Wattage is the power (heat) generated by your PV and the formula is Wattage = Voltage (of your battery) squared divided by Resistance (of your atty). eGo batteries are ~ 3.3v. If you are using a standard resistance atomizer (~3Ω), your Wattage reaches only 3.6 Watts, which is way too low. The recommended Wattage for cartomizers is somewhere between 4.5 and 7.5 Watts... So, first of all, get some LR cartomizers. I like LR Boge (2.0Ω) or 1.7Ω Smoktech single coil cartos (called Resurrectors at CCV). Both kinds are widely available; try Crystal Clear
vaping (free shipping) or Madvape--they carry both kinds
2) Try upping your nic level a bit, maybe up to 12-15 mg/ml. That's what I'm using and I like it.
3) You may also try an ejuice with a bit higher PG content, say 80/20 PG/VG.
That said, get some LR cartomizers first. That alone may just solve your problem.
Happy
vaping!
